Abstract
The invention discloses a quality testing method of a solar photovoltaic cable. The quality testing method comprises the following testing steps of: 1, placing the solar photovoltaic cable in a place with the environment conditions that the temperature is 90 DEG C and the humidity is 85%, carrying out air thermal aging test for 1000h, and after the test is finished, when the maximal change rate of the strength/elongation of the solar photovoltaic cable does not exceed +/-30%, judging the solar photovoltaic cable to be qualified in the test and carrying out a next testing step; and 2, placing the solar photovoltaic cable in a low-temperature refrigerating cabinet at -40+/-2 DEG C, carrying out a low-temperature test for 16 hours, and after the test is finished, when the solar photovoltaic cable has no cracks, judging the solar photovoltaic cable is qualified in the test and carrying a next testing step. The method disclosed by the invention is reasonable, the actual service environment of the solar photovoltaic cable is used during testing, so that the actual quality condition of the solar photovoltaic cable can be tested effectively, the actual service life of the solar photovoltaic cable can be measured, the quality problems are reduced, and the method has extensive popularization and application values.
Description
Technical field
The present invention relates to a kind of cable quality detection method, especially a kind of solar photovoltaic cable quality determining method.
Background technology
Electric wire is the second largest industry that is only second to automobile industry in the mechanical industry, is the requisite important auxiliary products of industry such as electrician, electric power, light industry, and its application relates to every field.To the household electrical appliance product, each link all be unable to do without electric wire from extra high voltage network, changes society in modern times and seems particularly important.Because electric wire manufacturing processing is simple, profit is higher, the industry access threshold is lower, has attracted numerous enterprises to add one after another, the electric wire that has formed nearly 8000 families in the present whole nation is made colony.In the vigor that has strengthened wires and cables industry greatly, also make present electric wire product quality, price vary.
Solar photovoltaic cable is meant the cable that is used for the solar energy photovoltaic system electric energy transmitting.In the solar photovoltaic systems, solar panels to power the control unit sets the path between the base for the outdoor laying completely naked exposed to the air, a long period of wind, sun, rain, frost and other harsh conditions.Under this application conditions, the performance requirement harsher than common cable also just arranged on performance for the stube cable that lays.But because China still also is in the starting stage to the research and development of photovoltaic cable, the production of this product does not still have national standard or industry standard can be complied with.
Existing solar photovoltaic cable manufacturer is when producing the solar photovoltaic cable product, and being still of being adopted is the common cable method of testing.Adopting existing method of testing to common cable that great shortcoming is arranged, is exactly that the method for testing that is adopted can't reach the actual environment for use situation of photovoltaic cable, can not react the actual mass of photovoltaic cable.Though make the product of a lot of manufacturers when test, can reach related standards, quality problems usually take place in product in actual use.
The method of testing of existing common cable has been not suitable for the quality test of solar photovoltaic cable.A kind of method of testing to the photovoltaic cable is badly in need of in solar photovoltaic cable production firm.
Summary of the invention
The objective of the invention is to overcome the deficiency in the existing testing lines method, a kind of method that more meets the photovoltaic wire cable test of photovoltaic product quality requirement is provided.
The technical scheme that the present invention adopted is: a kind of photovoltaic cable quality detecting method comprises following testing procedure:
Step 1, the photovoltaic cable is placed in 90 ℃ of temperature, humidity 85% environmental baseline; Carry out for the time 1000h the air thermal ageing test; Behind the EOT; The maximum rate of change of the intensity of solar photovoltaic cable/stretch rate is no more than ± and 30% o'clock, judge that this test passes carries out the next step test;
Step 2, solar photovoltaic cable is placed in-40 ± 2 ℃ of low temperature refrigerators, carries out 16 hours low-temperature test, behind the EOT, during photovoltaic cable free from flaw, carry out the next step test after judging this test passes;
Step 3, solar photovoltaic cable is positioned under the environment of ozone concentration 250～300ppm; Carry out anti-ozone test in 24 hours, behind the EOT, the photovoltaic cable is carried out 180 degree look inspection; When its sweep does not have cracking, judge and carry out the next step test after this test passes;
Step 4, the pH value and the conductivity of photovoltaic cable are measured, behind the EOT, PH weighted value>=4.3, conductivity weighted value≤10 μ S/mm, HCl content≤0.5%, fluorine content≤0.1% carry out the next step test after judging this test passes;
Step 5, solar energy hint cable is positioned under the UV radiation and condensation environment in manual simulation's the natural sunlight, the photovoltaic cable is carried out accelerated weathering test, record solar can be damaged required time by the photovoltaic cable;
Step 6, solar photovoltaic cable are placed in the loop program that at a certain temperature illumination and moisture replaces and are tested, and record solar can the photovoltaic cable appearance be damaged required time.
Test through step 1; The air aging property of photovoltaic cable under actual application environment can be effectively tested out,, the performance of photovoltaic cable under low temperature environment can be effectively tested out through the test of step 2; Test through step 3; Can test out the performance of photovoltaic cable under ozone environment, through the test of step 4, but the Halogen performance of the sunny ability of Validity Test photovoltaic cable; Through the test of step 5, step 6, effectively test out the actual life of photovoltaic cable.
The inventive method is reasonable; Use the actual environment for use of photovoltaic cable during test, but the actual mass situation of the sunny ability of Validity Test photovoltaic cable, the actual life that can measure the photovoltaic cable; Reduce product quality and ask, have promotion and application widely to be worth.
Embodiment
Combine specific embodiment that the present invention is made further explanation at present:
